Battery charge
When you finish the trip or the battery is running low,
charge it immediately.
Charging methods can be divided into two types: one
is to take out the battery and then charge it, the other
is to charge the battery directly on the electric bicycle.
First connect the charger to the charging port of the
battery (without connecting it to the socket) and then
to the mains. Connect it to a 220V / 50-60Hz power
supply.
There is an LED indicator on the power supply. The
LED is red when the battery is charging. The LED turns
green when the battery is fully charged.
Recommended charging time: 5-6 hours.
After charging, please unplug the input plug (from the wall outlet) first, and then
unplug the output plug (from the bike). The battery charger must have constant
voltage. Fluctuating voltage or fluctuating power supply of any kind can damage the
storage cells of the battery.
Checking the battery before using it for the first time
WARNING
• The battery is supplied partially charged. To ensure the full capacity of the battery,
please fully charge it before using it for the first time.
Battery care
• Even with proper care, rechargeable batteries don’t last forever. Each time the
battery is discharged and subsequently recharged, its relative capacity decreases by
a few percent. You can maximize the life of your battery by following the instructions
in this guide. The battery should be fully charged immediately upon receipt for the full
recommended charging time
• For a full 100% charge, leave the battery on the charger for a full hour after the
indicator light on the charger turns green.
• Lithium-ion batteries have no “memory”. Partial charge/discharge cycles will not
harm the batteries capacity or performance.
• The nominal output capacity of a battery is measured at 25ºC. Any variation in this
temperature will alter the performance of the battery and shorten its expected life.
High temperatures especially reduce the overall battery life and operating time.
• Always make sure to turn the bike’s ignition switch to “OFF” after each use. If you
leave the power switch in the “ON” position, or your electric bike has not been charged
for an extended period of time, the battery may reach a point where it will no longer
hold a charge.
